Stock index futures rose sharply on Wednesday after major central banks around the world announced coordinated actions to provide liquidity and U.S. private sector employment rose more than expected.

S&P 500 futures rose 29.7 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures gained 257 points, and Nasdaq 100 futures added 48.75 points.
